- Abstract
Rice being a big staple food, faces many abiotic stresses, resulting in a yield reduction. Iron (Fe) has many key roles for plants in sustaining growth and production, however, Fe toxicity is a big threat to rice production worldwide. There are many regulation mechanisms in rice to ensure an adequate supply of Fe to plant and to prevent deleterious effects. Rice is adopted many physiological and molecular mechanisms to cope with Fe toxicity in flooded soils, however, rice tolerance to Fe toxicity varies greatly and this mechanism has not fully understood. Efforts are being made to unfold the genetic basis of Fe toxicity tolerance in rice. There are many regulators discussed here, which are responsible for Fe uptake and transport from rhizosphere to the plants. Toxic effects of Fe on rice, the genes advocating the regulation of Fe, and many quantitative traits loci governing Fe toxicity tolerance in rice are discussed here. Many putative QTL involved in rice tolerance to Fe toxicity are presented in this review. The identification of QTL and regulators for Fe toxicity tolerance would be more helpful in regulating Fe toxicity and developing Fe tolerant lines in rice. More efficient breeding techniques are required to screen Fe tolerant rice genotypes. This review focused on some possible ways to improve Fe toxicity tolerance in rice and provide a strong theoretical base for future research.
